Intraoperative conversion rate to a large, limbal opening in minimally invasive strabismus surgery (MISS)

Abstract

This study confirms the reliability of the new MISS technique, and shows a low conversion rate to the usual limbal approach. The conversion rate decreased over time with increasing surgical experience. Muscle resections were associated with a higher conversion rate, while the age of the patient, the motility of the eye, revision surgery and the dose of surgery had no significant influence on an intraoperative conversion.

A Review of Minimally Invasive Strabismus Surgery (MISS): Is This the Way Forward?

“…In addition, muscle resections were associated with a higher conversion rate (P\0.001). Other factors like age, eye motility, primary versus revision surgery, and dose of correction did not significantly impact the likelihood of conversion [14].…”

“…Occasionally, intraoperative conversion to a large conjunctival opening may become necessary. In a retrospective study with 982 rectus muscle procedures from 451 consecutive patients operated on by one surgeon over a time span of 5 years, Kaup and coworkers [14] evaluated the conversion rate of MISS to a conventional surgical limbal opening. The authors reported an overall conversion rate of 3.6% (35/ 982) in their series.…”

Randomized control trial to compare minimally invasive strabismus surgery versus traditional limbal approach regarding postoperative ocular inflammation in Suez Canal University Hospital

“…Also, if the surgeons avoid a limbal opening, this will decrease postoperative visibility of the surgical procedure, patient discomfort, scarring around the operated muscles, and reduce hospital stay and working disability. [7][8][9] Switching to MISS at first will increase your surgical time.…”

“…while the age, the motility of eye and revision surgery had no significant influence on an intraoperative conversion. 9 So it is rapidly becoming the norm in medicine. 10 MISS can be used to perform all types of strabismus surgery, namely rectus muscle recessions, resections, plication's', transpositions, adjustable sutures, retroequatorial myopexy, oblique muscle recessions, reoperations, or plication's even in the presence of limited motility.…”
